getValueAbsolute() bug

[clearpicks]

When eSignal starts up, getValueAbsolute() doesn't show correct value in the following scenario. The EFS is applied to ($SPX, 5).
getValueAbsolute("day", 0, -1, vSymbol) should show the most current day (29, which is today ), but what shown is last Friday's date ( 26 ). After reload the EFS, the result returned becomes correct.


In Format Output window, after
the starting up, it looks like

26 29

After the reload, it is shown as

29 29
26 29







var vSymbol = null;
var vInterval = null;

var done;

function preMain() {
setPriceStudy(true);
setStudyTitle("Test");
done = false;

}


function main() {

var vInterval = getInterval();
if(vInterval == null)
return null;

if(vInterval == "D")
return null;

if(vInterval == "W")
return null;

if(vInterval == "M")
return null;

if(vInterval == "T")
return null;

if(vInterval > 5)
return null;

var nState = getBarState();

if ( nState == BARSTATE_ALLBARS ) {
done = false;
}

vSymbol = getSymbol() + ",D";

if ( getCurrentBarIndex() == 0 ) {
if ( done == false ) {
var d1, d0;
d1 = getValueAbsolute("day", 0, -1, vSymbol); d1 = d1[0];
d0 = getValue("day", 0, -1, getSymbol()+","+getInterval()); d0 = d0[0];

debugPrintln(d1 + " " + d0);

done = true;

}
}

}

Hello Clearpicks,

Thanks for bringing this to our attention. I'll pass your discovery along to our development team.

The code example below will correct the problem for you. When asking for "day" with getValueAbsolute(), it isn't necessary to pass the symbol as you did with vSymbol, which is most likely causing this problem.

var vSymbol = null;
var vInterval = null;

var done = false;

function preMain() {
    setPriceStudy(true);
    setStudyTitle("Test");
}


function main() {

    var vInterval = getInterval(); 
    if(vInterval == null)
    return null;

    if(vInterval == "D") return null;
    if(vInterval == "W") return null;
    if(vInterval == "M") return null;
    if(vInterval == "T") return null;

    if(vInterval > 5) return null;

    var nState = getBarState();

    if ( nState == BARSTATE_ALLBARS ) { 
        done = false;
    }

    //vSymbol = getSymbol() + ",D";

    if ( getCurrentBarIndex() == 0 ) { 
        if ( done == false ) {
            var d1, d0;
            d1 = getValueAbsolute("day", 0, 1); 
            d1 = d1[0];
            d0 = getValue("day", 0, -1, getSymbol()+","+getInterval()); d0 = d0[0];
            debugPrintln(d1 + " " + d0); 
            done = true;
        }
    } 
}

Hi,


I encountered this problem when I tried to use getValueAbsolute("high", -1, -1, "$SPX,D") to retrieve the previous day's high price. However it returned the high price of the day before yesterday. My testing script is only an example. The error not appears for every symbol. After the study is manually reloaded, the value returned becomes always correct. Also I remember I reported on daily chart, if the chart is left open before the trading session begins, esignal continues drawing the current day's data on the bar of previous day instead of creating a new bar. These two errors might be caused by the same bug in eSignal. Could you verify it for me? Thanks.

Hello Clearpicks,

Thank you for the details. I will look into this further.

[eSignal_JasonK]

Hello Clearpicks,

Can you give me a code example or a description of how to recreate the getValueAbsolute() error you encountered? I was not unable to reproduce this using a similar code example to your first one in this thread.

FYI, I haven't looked into the second error yet, but I plan to tomorrow morning.

[eSignal_JasonK]

Hello Clearpicks,

I was able to reproduce the bug with getValueAbsolute() today and will report it to our development team.

Hello Clearpicks,

I need a few more details in regards to the problem you reported with the daily interval. I haven't been able to reproduce this problem yet on build 608.

Also I remember I reported on daily chart, if the chart is left open before the trading session begins, esignal continues drawing the current day's data on the bar of previous day instead of creating a new bar.

Which build did you report this problem with? Are you able to reproduce this bug currently? If so, what symbol(s) and time template are you using? Do you launch eSignal prior to the market open or are you leaving it connected overnight?

[clearpicks]

Hi JasonK,

I am using build 608. I will try to reproduce the problem tomorrow. Right now I just always start eSignal a few seconds after the market is open, therefore I don't know whether the problem is fixed or not. Because I am using the same version as the one when I reported the bug, I doubt it has been fixed untill the error was caused by the server side.

Hi JasonK,


The problem is still there. See the attached screenshot. I captured it at arround 09:31AM. The price was drawn on yesterday's bar.

Hello Clearpicks,

I saw the problem this morning with $SPX on build 608. We're looking into this issue with our current beta. If it has not been addressed in the current beta, we'll report this problem again to the development team. I'll keep you posted.
